The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
So, what I recommend doing and what I personally do is I will turn off overhead lights in the afternoon. It's not completely dim. It's not completely dark, but I will start to reduce the amount of overhead light and just simply keep the light pad on and whatever other lamps I happen to be using.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
The idea is that in this so-called phase two of the 24-hour cycle, from about 9 to 16 hours after waking, you want to bring the level of lights down a bit. Having lights that are in front of you is fine, but overhead lights at that time are not going to be optimal for the sorts of neurochemical states that your brain wants to be in.
